TSW-125-15-S-D Equivalent & Substitute Parts

Part Overview

The TSW-125-15-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 50-position connector operates across the temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity level rating. Substitute parts are identified to provide alternative options when the primary part is unavailable or when specific mechanical configurations are required for application requirements.

Substitute Part Grouping Explanation

The TSW-125-15-S-D has one identified substitute part: TSW-125-14-S-D. Both parts share the same manufacturer (Samtec Inc.), series designation (TSW), and base product number (TSW-125). Substitution eligibility is determined by the following critical parameters that remain constant across both parts:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 50
• Number of rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row spacing - Mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Contact shape: Square
• Contact finish - Mating: Gold
• Contact finish - Post: Tin
• Contact material: Phosphor Bronze
• Insulation material: Polybutylene Terephthalate (PBT)
• Operating temperature: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Insulation color: Black
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The primary difference between these parts is the contact length - mating dimension, which affects the overall contact length and insulation height characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-125-15-S-D and TSW-125-14-S-D maintain active product status with identical compliance certifications including ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status. Selection between these parts is determined by the mechanical requirement for contact length - mating dimension. The TSW-125-15-S-D provides a longer mating contact length of 0.520" (13.21mm) with an overall contact length of 0.730" (18.54mm), while the TSW-125-14-S-D provides a shorter mating contact length of 0.320" (8.13mm) with an overall contact length of 0.530" (13.46mm). The choice between these parts depends on the specific board thickness and mating depth requirements of the application. Both parts are suitable for through-hole mounting with solder termination and maintain identical electrical and thermal performance characteristics across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between TSW-125-15-S-D and TSW-125-14-S-D?

A: The primary difference is the contact length - mating dimension. The TSW-125-15-S-D has a mating contact length of 0.520" (13.21mm), while the TSW-125-14-S-D has a mating contact length of 0.320" (8.13mm). This results in different overall contact lengths of 0.730" (18.54mm) and 0.530" (13.46mm) respectively.

Q: Are these parts electrically equivalent?

A: Yes. Both parts share identical contact materials (Phosphor Bronze), contact finishes (Gold mating, Tin post), pitch specifications (0.100" / 2.54mm), and operating temperature ranges (-55°C to 125°C). The electrical performance is equivalent.

Q: Can I use TSW-125-14-S-D as a direct replacement for TSW-125-15-S-D?

A: Substitution depends on the mechanical requirements of your application. The shorter mating contact length of the TSW-125-14-S-D may not be suitable if your application requires the deeper mating depth provided by the TSW-125-15-S-D. Verify that the board thickness and mating depth requirements are compatible with the substitute part's contact length specifications.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, are REACH unaffected, and have moisture sensitivity level 1 (unlimited). Compliance certifications are identical.

Q: What is the row spacing for these connectors?

A: Both parts have a row spacing - mating of 0.100" (2.54mm), which matches the pitch specification. This maintains a 2-row configuration with 25 positions per row.
